[0009] Reference is made to FIGS. 1 to 5, which show a preferred embodiment of an adjustable arm device for cable training of the present invention. However, this embodiment is for illustrative purposes only and is not intended to limit the patent application to this structure.

[0010] The said adjustable arm device for cable training 100 is designed to be mounted on an existing vertical frame 10 to provide guidance and positional support for a training cable 20, where the end of the training cable 20 is equipped with a grip 21. The adjustable arm device for cable training 100 includes: a mounting base 30, fitted on the vertical frame 10 with an adjustable height; a locking component 40, provided on the mounting base 30 to lock the height position of the mounting base 30; a swing arm 50, including a connecting end 51 and an extending end 52, where the connecting end 51 is connected to the mounting base 30, and a guide pulley 53 is rotatably provided on the connecting end 51 for the training cable 20 to be in a sliding contact relationship; a swivel pulley housing 60, rotatably disposed on the extending end 52 of the swing arm 50 via a rotary shaft 61. The swivel pulley housing 60 includes a cable outlet 62 and an end pulley 63. The end pulley 63 is rotatably disposed at a position adjacent to the cable outlet 62 so that the end of the training cable 20 first slides and contacts the end pulley 63 before passing out through the cable outlet 62; a vertical adjustable joint 70, installed at the connecting end 51 of the swing arm 50. The vertical adjustable joint 70 includes a horizontal support shaft 71, a vertical positioning seat 72, and a vertical angle locking component 73. The swing arm 50 can perform a vertical swinging motion to adjust the angle with the horizontal support shaft 71 as the pivot point. The vertical positioning seat 72 is equipped with several vertical angle slots 74, and the vertical angle locking component 73 can selectively lock with any one of the vertical angle slots 74 to fix the state of the vertical adjustable joint 70; a horizontal adjustable joint 80, installed on the mounting base 30 and relatively positioned below the vertical adjustable joint 70. The horizontal adjustable joint 80 includes a vertical support shaft 81, a horizontal positioning seat 82, and a horizontal angle locking component 83. The swing arm 50 can perform a horizontal swinging motion to adjust the angle with the vertical support shaft 81 as the pivot point. The horizontal positioning seat 82 is equipped with several horizontal angle slots 84, and the horizontal angle locking component 83 can selectively lock with any one of the horizontal angle slots 84 to fix the state of the horizontal adjustable joint 80; and a cable passage 54, formed between the connecting end 51 of the swing arm 50 and the swivel pulley housing 60 at the extending end 52, allowing the training cable 20 to form a bent passage segment 22 corresponding to the cable passage 54.

[0011] As shown in FIGS. 1, 3 and 5, in this embodiment, a handle 90 is further provided on one side of the mounting base 30. The function of the handle 90 disclosed in this embodiment is primarily to provide the user with a structure to firmly grip and support the mounting base 30 when operating the locking component 40, making its use safer and more convenient.

[0012] As shown in FIG. 2, in this embodiment, the bent passage segment 22 of the training cable 20 extends upwardly after passing through the guide pulley 53 disposed at the connecting end 51 and is thus in a relatively distant relationship to the horizontal positioning seat 82 of the horizontal adjustable joint 80.

[0013] As shown in FIGS. 3 and 4, in this embodiment, the vertical frame 10 forms multiple positioning holes 11 arranged at intervals, while the locking component 40 provided on the mounting base 30 is a spring-loaded pin type including a pull knob 41, a reset spring 42, and a locking end 43. The locking end 43 can selectively engage with any one of the positioning holes 11.

[0014] As shown in FIGS. 1 and 2, in this embodiment, a stop ball 23 is threaded through the end of the training cable 20. The outer diameter of the stop ball 23 is larger than the cable outlet 62, and thus is blocked outside of the cable outlet 62 to prevent the end of the training cable 20 from retracting backward.

[0015] As shown in FIG. 5, in this embodiment, the connecting end 51 of the swing arm 50 includes two side plates 55 spaced apart from each other such that the vertical positioning seat 72 of the vertical adjustable joint 70 can be located between the two side plates 55. The vertical angle slots 74 provided on the vertical positioning seat 72 are in the form of holes, while the vertical angle locking component 73 is disposed on one of the side plates 55. The vertical angle locking component 73 is a spring-loaded pin type including a pull control mechanism 731, a spring 732, and an insertion end 733. The insertion end 733 is selectively engageable with any one of the vertical angle slots 74.

[0016] As shown in FIG. 5, in this embodiment, a reinforcing support rod 56 is also assembled between the two side plates 55, and the vertical positioning seat 72 is correspondingly formed with an arcuate opening 725 to allow the reinforcing support rod 56 to pass therethrough. The main function of the reinforcing support rod 56 disclosed in this embodiment is to produce a reinforcing support effect between the two side plates 55 to increase their load-bearing strength.

[0017] Through the above structural composition and technical features, the practical application of the adjustable arm device for cable training 100 disclosed in the present invention, as shown in FIG. 9, can be mounted on the vertical frame 10 of existing multi-functional sports fitness equipment, thereby providing guidance and positional support for the training cable 20. The end of the training cable 20 is equipped with the grip 21 for the user to hold and exert force to achieve the purpose of training, while the other end of the training cable 20 is connected to a counterweight component 12 to form a load effect. The present invention can mainly provide an innovative adjustable arm device structure for cable training with versatile and flexible joints, which are explained as follows: first, with respect to the vertical adjustable joint 70, as shown in FIG. 6, it allows the swing arm 50 to perform a vertical swinging motion to adjust the angle with the horizontal support shaft 71 as the pivot point, and uses the vertical angle locking component 73 to lock its vertical angle state; next, with respect to the horizontal adjustable joint 80, as shown in FIG. 7, it allows the swing arm 50 to perform a horizontal swinging motion to adjust the angle with the vertical support shaft 81 as the pivot point, and uses the horizontal angle locking component 83 to lock its horizontal angle state; and then, with respect to the swivel pulley housing 60, as shown in FIG. 8, since the swivel pulley housing 60 is rotatably disposed on the extending end 52 of the swing arm 50 through the rotary shaft 61 (as shown in FIG. 2), it allows the swivel pulley housing 60 to perform a swinging motion with the rotary shaft 61 as the pivot point, which makes the grip 21 at the end of the training cable 20 also capable of performing a swinging motion (as shown by arrow LI in FIG. 8). Therefore, the present invention allows the user to smoothly achieve pulling actions at various angles during cable operation, thus enabling the user to have comprehensive cable training.
